中文摘要：
重分析方法作为一种能够根据初始计算结果快速估计修改后结构的快速计算方法，近几十年来得到了广泛研究，并取得了一系列具有理论价值和工程意义的成果，在机械、土木等结构设计领域得到了广泛的应用。随着复杂产品设计对数值计算性能要求的不断提升，重分析方法必将在各个学科领域起到重要的作用。为此，该文从静态和动态的角度出发，分别对重分析理论的两类主要方法：直接法和近似法展开了深入地讨论，通过对目前主要重分析方法的发展现状和主要成果的分析和研究，对未来重分析方法的发展方向提出了几点建议。
英文摘要：
Reanalysis is a fast computational method to predict the response of a modified structure based on its initial analysis results. Due to its advantages in efficiency, the reanalysis method has made a significant progress in recent several decades. With the increase of requirements for computational performance in numerical methods, the reanalysis method should play a more important role in complex product design. Therefore, this paper investigates and discusses some characteristics of recent developed directions and approximation methods from the view point of static and dynamical problems. Moreover, some suggestions for advancing the reanalysis method have been also given according to the state of the art reanalysis.
